Here is Donna's third and final post of her fantastic series on baby budgeting: milk. Considering how much trouble I am having breastfeeding, I won't be lying if I were to say that I get very tempted to switch on over to formula. However, I will persevere for the time being and if I do end up going the formula route in the future, this is another post I will have bookmarked. Donna has also graciously offered to give away a $5 Amazon e-certificate. Just leave a comment to this post by Friday, 11/5/2010 and a winner will be chosen by a random number generator. Be sure to include your email address so that we can contact you if you win. Good luck,...
